However, their framework is insufficient to construct strongly secure threshold schemes, such as threshold signatures and threshold public-key encryption, etc.\r\n\r\nIn this paper, we strengthen the security definition for a universal thresholdizer and propose a scheme which satisfies our stronger security notion. Our UT scheme is an improvement of Boneh et. al ’s construction at the level of threshold fully homomorphic encryption using a key homomorphic pseudorandom function. We apply our strongly secure UT scheme to construct strongly secure threshold signatures and threshold public-key encryption.","lang":"eng"}],"title":"Strongly secure universal thresholdizer","doi":"10.1007/978-981-96-0891-1_7","OA_place":"repository","page":"207-239","publication":"30th International Conference on the Theory and Application of Cryptology and Information Security","date_created":"2025-01-05T23:01:56Z","isi":1,"month":"12","intvolume":"     15486","oa":1}
